Nonsense.
You don't have to have a bare bones system to be free of problems.
You have absolutely NO idea how many people are having this issue....it might be specific to that particular program. You have NO idea if there are any geolocation issues in Delaware. You have NO idea whether people are being "hit with problems" en masse.
You're making stuff up again. Adding 2 and 2 and getting 27.
One swallow does not a summer make (unless you're Joanne from the summer I spent near the beach in 1989....)
I can estimate how many people face this problem now that the cause has been identified. The cause is a rather popular piece of software, so a significant number of people face this issue because this piece of software conflicts with the Delaware casino application. As it's a false positive, it is likely to happen with other pieces of software.
The designers of the Delaware system should have thought of this, but it seems they decided to let the customers do their testing and diagnostics for them. Unfortunately, they have been unhelpful with the instructions so that when faced with such an issue, the customer is faced with a vague error message that makes it hard to pin down the cause.
There are other solutions apart from the bare bones system, but they are more technically challenging. Most people buy an off the shelf PC with everything already installed and configured, with the most technical challenge faced then being the installation of new software, expecting it to work provided the step by step instructions are followed. Diagnosing an issue from error messages that are not fully documented in the users guide is not something most customers can do. We see here how unhelpful CS often is when the regular crop of casinos cause odd errors for players. There is no users guide for these softwares, so when a player gets "casino error 2" they expect the CS department to tell them in plain English what is wrong and how to fix it. This rarely happens, and the most common reply is "turn off your anti virus and firewall and try again".
What the Delaware operators need to do is EXPLAIN in PLAIN ENGLISH what they mean by "remote control software", as well as list those products that they know will cause the problem and should be removed before using their casino.
The problem here is that players could be faced with having to remove software they use on a regular basis, so would be faced with uninstalling it to play, but having to reinstall it when they want to use it. This is where a second PC looks like a very good solution, as the softwares that conflict can be on different machines.
I expect an IT expert could come up with a bespoke single PC solution to the problem, but they are unlikely to do this for free. There are however, guides on the Internet on such customisations, some better than others. Some manufacturers and software designers do not like these guides, as some fix things that are intentionally broken by the manufacturer or software designer. Apple don't like them for sure ;-)
This is a case of something being "intentionally broken" by the designers of the Delaware casino, as they have deliberately created this conflict that prevents the casino from working when certain other software is installed on the system.
A guide they would like would say "remove the offending software", but equally there could be a guide on how to get the casino to work alongside the offending software. These guides will be produced because a demand has been created for a solution.
The idea they may not like is to change the name of the offending process so that it looks more "innocent". If they are scanning process names, this move will fool the software. This would not just work with registry mechanic, but also with a true "remote control software" on the list they are intending to ban.
